Python accessing nested lists

Question

How do I access the every elements in index(3) in the nested list ?

Phones = [[‘Iphone11’, ‘Apple’, 6.1, 3110, 1280],
[‘GalaxyS20’, ‘Samsung’, 6.2, 4000, 1348],
[‘Nova 5T’, ‘Huawei’, 6.26, 3750, 497],
[‘Reno Z’, ‘Oppo’, 6.4, 4035, 397]]

For example:
I want to access index(3) in the list of phones
Which return would [[3110,4000,3750,4035]]

Answer 1

Try this
L= []
For item in Phones:
L.append(int(item[3]))
print(L)

In first iteration item will represent 1st list, in second iteration the second list & so on...

Answer 2

# with list comprehension:

res = [lst[3] for lst in Phones]
